Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers(志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a verve activity(神經(jīng)活動), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.
【小題1】According to Professor Barnes, theobromine ______.

Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled—to $1. 01 per pack—smokers have jammed telephone “quit lines” across the country seeking to kick the habit.   
This is not a surprise to public health advocates. They’ve studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase.  
The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely.   
In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost ＄10.06 at one drugstore Wednesday. Charleston, S, C., where the 7-cent-a-pack tax is the lowest in the nation. The price was $4. 78.  
The influence is obvious.   
In New York, high school smoking hit a new low in the latest surveys—13.8%, far below the national average. By comparison, 26% of high school students smoke in Kentucky, Other low-tax states have similarly depressing teen-smoking records.   
Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans “who choose to smoke.”  
That’s true, But there is more reason in keeping future generations of low-income workers from getting hooked in the first place, As for today’s adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better.  
66 The text is mainly about___________.   
A. the price of cigarettes                       B. tie rate of teen smoking  
C. the effect of tobacco tax increase              D. the differences in tobacco tax rate  
67 What does the author think is a surprise?  
A. Teen smokers are price sensitive.  
B. Some states still keep the tobacco tax low.   
C.  Tobacco taxes improve public health.   
D.  Tobacco industry fiercely fights the tax rise.   
68. The underlined word "deter” in Paragraph 3 most probably means ______ .   
A. discarding    B. remove    C. benefit      D. free  
69. Rogers’ attitude towards the low-income smokers might be that of _____ .  
A. tolerance   B. unconcern    C. doubt   D. sympathy  
70. What can we learn from the last paragraph?  
A. The new tax will be beneficial in the long run.   
B. Low-income Americans are more likely to fall ill.  
C. Future generations will be hooked on smoking.   
D. Adults will depend more on their families.

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。
__【小題1】__ Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge(隆起) structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. __【小題2】_ Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer’s ink. They can be recorded easily. __【小題3】_ Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. __【小題4】_ When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect(察覺) with the naked eye. __【小題5】__ Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

I know what you’re thinking: pizza? For breakfast? But the truth is that you can have last night’s leftovers in the morning if you want to.
I know lots of women who don’t have breakfast, and they have many different excuses for doing it. Some say they don’t have time, others think they’re “saving” calories（卡路里）, still others just don’t like breakfast food.
But eating in the morning is very important when you’re trying to lose weight. Eating just about anything from 300 to 400 calories would be better than nothing at all.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers found that those who don’t have breakfast have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,”I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
【小題1】The word “l(fā)eftovers” in Paragraph 1 probably means __________.
